The IBD Sector Leaders stock broke out earlier, but has fallen back below the prior 51.59 entry from a consolidation. If a stock you're watching clears a buy point then retreats 7% or more below the original entry price, it's considered a failed base. It's best to wait for the stock to form a new base and breakout. Also understand that the most recent consolidation is a later-stage base, which makes it riskier to establish a new position or add shares to an existing one.
